Abstract

La présente invention concerne un support d'enregistrement sur lequel un fichier multimédia multipiste est enregistré, un procédé destiné à éditer un fichier multimédia multipiste, et un appareil destiné à éditer un fichier multimédia multipiste. La présente invention active l'appareil d'édition de fichier multimédia pour mémoriser un fichier multimédia multipiste contenant au moins une piste audio et au moins une piste vidéo correspondant à la piste audio, générer une valeur de réglage de volume en fonction d'une commande de réglage de sortie entrée par l'utilisateur en vue de régler la sortie de la piste audio ou vidéo, et enregistrer la valeur de réglage de volume dans le fichier multimédia multipiste. Selon la présente invention, l'utilisateur peut insérer sa voix dans un fichier multimédia tel qu'un fichier vidéo musical à la place d'un son audio existant, ou sa vidéo prise directement à la place d'une vidéo existante, ce qui lui permet de produire le fichier multimédia unique qu'il souhaite.
